monitoring path.

The monitoring slider controls the hardware monitoring level (ASIO direct

monitoring) but does not control the software monitoring. Its default

position is in front of the bold dot. It can be set independently for each

channel. This is directly controlled from the host application using its

monitoring mixer.

temporary CPU overload.

To avoid the loss of synchronization between input and output signals,

HOW TO CHECK THE INSTALLATION

Is the card properly installed under MacOS?

Double click on the VXpocket 440 icon. This launches the VX Control

panel. It should display the card and its serial number, and it should be

possible to change the sampling frequency.

You can also check that the inputs and outputs of the card are displayed in

control panel: sound.

Is the card properly installed under Windows?

The inputs and outputs of the card should be selectable from control

panel, multimedia (or sound & multimedia, or sound, depending on the

Windows version), and system sounds can be played from here.

The VXpocket 440 channels, through the wave driver, are named:

- VXpocket 440 out #1 and VXpocket 440 out #2 for the outputs.

- VXpocket 440 in #1 and VXpocket 440 in #2 for the inputs.

The VXpocket 440 channels, through the DirectSound driver, are named:

- VXpocket440 audio card stereo1 and VXpocket440 audio card stereo2 for the

outputs.

- the inputs are not available through DirectSound under Windows 2000

and XP.

If only the DirectSound channels are displayed, this means the wave driver

has not been installed properly (which is not a problem if you don't need

to use the wave driver).
